Bought a 500 cm new in 1978-9.Did not take long to start using it for weddings and beautiful snap shots of my then young kids, 100's of them.Used mostly a pistol grip and metered view finder ( a must for trying to follow a 3 to 7 yr old and pan also) some times my 650 or 550 Sunpak flash with a cheap old flash bracket, the 550 had a thyristor circuit so only had to keep track of F stop.

Some times would sit in the back yard with the 150mm lens and a tripod to record the action, best pictures I have are of family taken with that camera.
